The radial symmetry is observed in
Platyhelminthes
II. Coelenterates

IV. Annelids
v) Echinoderms
The correct statements are

Options

A. ii and v only
B. I,ii,iii and v only
C. ii, iii and I only
D. I, iii and v only

Answer

To determine which of the given groups exhibit radial symmetry, we can analyze each option step by step:

### Step 1: Understand Radial Symmetry
Radial symmetry refers to the arrangement of body parts around a central axis, allowing the organism to be divided into similar halves through multiple planes. This type of symmetry is commonly found in certain groups of animals.

### Step 2: Analyze Each Group
1. **Platyhelminthes (Flatworms)**: These organisms exhibit bilateral symmetry, not radial symmetry. They have a distinct head and tail region.

2. **Coelenterates (Cnidarians)**: This group includes jellyfish, corals, and sea anemones, which exhibit radial symmetry. They can be divided into similar halves along multiple planes.

3. **Aschelminthes (Nematodes and Rotifers)**: These organisms also exhibit bilateral symmetry, not radial symmetry.

4. **Annelids (Segmented Worms)**: Annelids show bilateral symmetry as well, with a clear head and tail end.

5. **Echinoderms (Starfish and Sea Urchins)**: Echinoderms exhibit radial symmetry, especially in their adult forms, where they can be divided into similar halves around a central axis.

### Step 3: Conclusion
From the analysis:
- **Coelenterates** (option II) and **Echinoderms** (option V) exhibit radial symmetry.
- **Platyhelminthes** (option I), **Aschelminthes** (option III), and **Annelids** (option IV) do not exhibit radial symmetry.

Thus, the correct statements regarding radial symmetry are options II and V.

### Final Answer
The correct statements are: **II. Coelenterates and V. Echinoderms.**
